KINDS OF PLANTS 



only an arbitrary distinction; a small tree is called a 

 tree-like shrub, while a shrub attaining to .30 feet in 

 height is referred to under the same term. The line 

 between the two cannot be sharply defined. 



Climbers are plants of weak stems, sometimes 

 tali and sometimes low growing, which cannot Kft 

 themselves without the aid of some support. They 

 may be in any one of the classes mentioned above and 

 they may have woody or juicy stems. Those which 

 twine around their support are, strictly speaking, 

 vines; chmbers raise themselves by means of tendrils, 

 aerial rootlets or some special device provided for the 

 purpose. Thus all vines are climbers, but all chmb- 

 ers are not vines. Nurserymen commonly mean tall 

 growing plants when they use the term climber; lower 

 growing kinds they define as trailers. 



A difference of a single degree of latitude has a 

 marked effect on many plants, though it is not distance 

 north or south alone that tells. Some regions, for 

 instance, from their topographical peculiarities, may be 

 particularly adapted to the growth of certain things 

 which ordinarily would not be hardy in that latitude; 

 while possibly other locaKties further south are unfav- 

 orable, by reason of their configuration, to the cultiva- 

 tion of even lustier species. Altitude enters into the 

 matter to a certain degree, likewise the texture of the 

 soil, the proximity of large bodies of water and the 

 direction of the prevaiHng winter winds. 



The knowledge that all perennials are not as easily 

 raised from seed as most annuals, and that the latter
